Chatroulette is a website that pairs random strangers from around the world together for webcam-based conversations. Visitors to the website randomly begin an online chat (video, audio and text) with another visitor. At any point, either user may leave the current chat by initiating another random connection. The Chatroulette web site was created by Andrey Ternovskiy, a 17-year-old high school student in Moscow, Russia.

The site is notorious for explicit sexual behavior by some users.
